Do you honestly believe that it's more efficient for two (or more) different companies to lay down the communication hardware necessary for cable service, including broadband internet, that for there to be only one?
It's the same problem as electric or water service. It makes no sense for two companies to lay down water pipes serving the same area, so why does it make sense for cable?
The physical network aspect of cable, and broadband internet, is a natural monopoly, because of the amount of infrastructure investment required to create it.
Now if you want to talk about content providers, that's a different story. That is why broadband internet needs to be regulated as a "common carrier," to prevent situations like Comcast throttling NetFlix in favor of their own On Demand offerings.
Perhaps you should think a little before casting aspersions ("What crack are you smoking") on those you disagree with? Or do you enjoy being seen as an arrogant jerk?
